摘要:
A light marker adapted to be indwelt in the vicinity of a lesion inside an organ of an object, the light marker emitting light to be picked up at an outside of the organ to allow a location of the lesion to be identified based on a position of the light on a resultant pickup image, wherein the light marker comprises liquid composed of viscous substance mixed with fluorescent substance (214) and adapted to be injected to a site underneath a mucous membrane (302) of the lesion (100). A method of identifying a location of interest on an inside wall of a tubular object to be examined, the tubular object having a wall permitting light to be transmitted therethrough using the light marker.

摘要:
A lesion identification system for surgical operations has a light marker adapted for placement in the vicinity of a lesion inside an organ of an organism, and a location-identifying device (14) detecting a light emitted from the light marker (12) at an outside of the organ for identifying a location of the lesion. The marker includes a light emitter and an engagement member associated with the emitter to be engageable with a wall of the organ. The engagement member includes a clip. The light emitter emits light with a wavelength in a near-infrared range. The device includes an endoscope comprising an inserter section having an image pickup element picking up a reflected light, involving the light from the light marker, at an outside of the organ, and an image pickup unit allowing the reflected light, picked by the image pickup element, to be generated as an image for display on a monitor.
摘要:
An ultrasonic endoscope (12) includes an elongated insertion section (22) and an operation section (24). The elongated insertion section (22) has a distal end and a proximal end. The operation section (24) is provided at the proximal end of the insertion section. The insertion section includes a distal end hard portion (32) having a distal end surface at the distal end, the distal end surface of the distal end hard portion including an ultrasonic transducer (42), a forceps channel opening portion (38a) and an object lens (44) on a straight line.
摘要:
An ultrasonic endoscope (10) includes an insertion section (12), an operation section (14), an optical observation system and an ultrasonic observation system. The insertion section has a distal end and a proximal end. The operation section is disposed on the proximal end of the insertion section. The optical observation system is disposed in the insertion section. The optical observation system has an objective lens (38) on a distal end surface of the insertion section. The ultrasonic observation system is disposed in the insertion section. The ultrasonic observation system has an ultrasonic transducer (52; 52a; 52c) on the distal end surface of the insertion section or further forward than the distal end thereof. A focal position of the optical observation system and a scanning surface of the ultrasonic transducer are approximately on the same plane.
